[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of a vaginal speculum used for artificial fertilization of livestock and diagnosis of genital diseases.

[0002]

[Prior art]

 Generally, when diagnosing artificial fertilization in cows at an appropriate time, or when diagnosing pregnancy status or genital diseases, a vaginal speculum is inserted into the vagina and opened, and the cervical canal and vaginal mucus properties are observed. .

As shown in FIG. 5, a conventional vaginal mirror 1 for domestic animals is constructed by combining two metallic expansion pieces 2 a, 2 b having a C-shaped cross section, and a gripping portion 3 on the proximal end side of which is provided with a shaft 4. It is connected in a divider-like manner so that it can be opened and closed, and a screw rod 6 having a handle 5 attached thereto is laterally passed through the grip portion 3 of the one extension piece 2a, and the tip end thereof is brought into contact with the inside of the other extension piece 2b. By rotating the handle 5, the distance between the extension pieces 2a and 2b can be adjusted.

When the conventional metal vaginal mirror 1 for livestock is inserted into the vagina of a cow for diagnosis, the handle 5 is rotated to close the expansion pieces 2a and 2b, and then the warm pieces are warmed in warm water. Hold the holding part 3 in the hand and insert it into the vagina 9 of the cow as shown in FIG. After that, the handle 5 is rotated to open the tip side of the expansion pieces 2a and 2b, and while holding the vaginal mirror 1 for livestock with one hand, brightly illuminate the inside of the vagina 9 with the penlight in the other hand. The vaginal mucus properties of the cervix 10 and vaginal wall 11 were observed.

However, the conventional vaginal mirror 1 for a domestic animal opens in a divider shape at the tip side. Therefore, when the vagina 9 is inserted into the vagina 9 and the expansion pieces 2a, 2b are spread, the cow is sore and violent that it is difficult to make a diagnosis. . At this time, the vaginal wall 11 contracts, which makes it difficult to see, and the left and right vaginal walls 11 spread by the opening pieces 2a and 2b are hidden and invisible, so that the state of the entire vagina cannot be observed. Also, the conventional vaginal mirror 1 for animals is heavy and difficult to handle because it is made of metal, and the gripping part 3 side is heavy and difficult to balance, so it is pushed out even if it is inserted into the vagina 9, and it comes out. Therefore, when the vaginal wall 11 contracted, it was even easier to pull it out, and I had to hold it down with one hand.

In addition, there are cases where urine is guided for the diagnosis of diseases such as ketosis, and in this case also, the vaginal mirror 1 for livestock is inserted into the vagina 9 and the expansion pieces 2a and 2b are opened, and the rubber is removed. A urethral catheter made of urethra was inserted into the urethral meatus and pumped up. However, there is a suburethral diverticulum in front of the external urethral opening of the cow, and usually the external urethral opening is closed and cannot be seen.If the vaginal wall 11 is contracted, the external urethral opening is searched and the urethral catheter is accurately located. It was difficult to insert.

[0007]

[Problems to be solved by the device]

 The present invention eliminates the above drawbacks, is lightweight and easy to insert into the vagina, does not cause pain to livestock when inserted, and is securely inserted without coming out of the vagina during examination, and the external urethral meatus protrudes to simplify the urethral catheter. It is intended to provide a vaginal mirror for livestock that can be inserted into a urine and can be easily operated.

[0008]

[Means for Solving the Problems]

 The present invention has a transparent plastic cylindrical body with both ends open, a slotted slit formed in the middle of the cylindrical body, and a slit longer than the cylindrical body. It is characterized by consisting of a warhead-shaped guide rod.

[0009]

[Action]

 When making a diagnosis by inserting the vaginal mirror for livestock of the present invention into the vagina of livestock, insert a guide rod into the cylindrical body and combine it, hold the grasping part in the state with the guide part at the tip protruding, and place it inside the vagina. insert. After that, when the guide rod is pulled out from the cylindrical body, the cylindrical body is held in the vagina. Next, a penlight is attached to the opening edge of the cylindrical body to observe the cervical canal and vaginal mucus properties of the vaginal wall while illuminating the inside of the vagina. When urinating for diagnosing illness, the cylindrical body is rotated, and if a slot-shaped slit is located at the external urethral meatus, the outer urethral meatus rises inward from the slit, so the urethral catheter is removed. Can be easily inserted into the urethral meatus.

【Example】

 Hereinafter, the present invention will be described in detail with reference to FIGS. This vaginal mirror 12 for domestic animals is composed of a transparent plastic cylindrical body 13 having open both ends, an elongated slit 14 formed in the middle of the cylindrical body 13, and a guide rod 15. The cylindrical body 13 is formed of a transparent plastic such as acrylic resin which is hard to be scratched, has excellent heat resistance and can be sterilized by boiling. In addition, an elongated slit 14 is formed in the middle of the cylindrical body 13 along the longitudinal direction of the cylindrical body 13.

Further, the guide rod 15 is formed of plastic, and a guide portion 16 having a warhead shape having an outer diameter slightly smaller than the inner diameter of the cylindrical body 13 is provided at the tip, and the guide rod 15 is larger than the inner diameter of the cylindrical body 13 at the base end portion. An outer diameter grip portion 17 is formed. Further, reinforcing ribs 18 are radially attached to the outer periphery of the guide rod 15. This guide rod 15 is formed to be longer than the cylindrical body 13 so that the guide portion 16 having a warped end at the tip of the guide rod 15 slightly protrudes from the cylindrical body 13 when inserted into the cylindrical body 13 so that the guide rod 15 can be inserted and removed freely inside. It has become.

When the vaginal mirror 12 for livestock having the above-mentioned configuration is inserted into the vagina 9 of a cow to diagnose the appropriate period of artificial fertilization, the state of pregnancy, or the diagnosis of genital disease, a cylindrical body 13 is formed as shown in FIG. With the guide rod 15 inserted and the guide portion 16 at the tip slightly projected, the grip portion 17 is held in the hand and inserted into the vagina 9. At this time, the vaginal mirror 12 for livestock has a projecting bullet-shaped guide portion 16 so that the cow can be easily inserted without causing pain. After that, when the guide rod 15 is pulled out from the cylindrical body 13 as shown in FIG. 4, the cylindrical body 13 is held in the vagina 9.

After that, the clip 21 of the penlight 21 is inserted and held in the opening edge portion of the cylindrical body 13. In this way, the vaginal mucus properties of the cervical canal 10 and vaginal wall 11 are observed while illuminating the inside of the vagina 9 with the penlight 21. Since the cylindrical body 13 is made of transparent plastic, it is possible to observe the entire vaginal wall 11 in detail, and since the cow does not hurt, the vaginal wall 11 does not abnormally contract and the normal state is observed. it can. Moreover, it is not necessary to hold the grip portion 3 with one hand and observe the penlight with the other hand as in the conventional case, and both hands can be used freely, so that the diagnosis work is easy.

When urinating for the diagnosis of a disease such as ketosis, the cylindrical body 13 is rotated and the slit 14 having a long hole is located at the external urethral opening 22. It rises from the slit 14 to the inside. In this case, the suburethral diverticulum 23 in the front does not rise through the slit 14 and only the external urethral meatus 22 projects into the cylindrical body 13. Therefore, a rubber urethral catheter 24 can be inserted from the open end of the cylindrical body 13 and easily inserted into the external urethral meatus 22 protruding from the slit 14. For this reason, two people used to perform urinary work in the past, but now it can be done easily by one person.

The guide rod 15 may be formed by a pipe or a round rod whose tip is curved like a warhead. In addition, although the above-mentioned embodiment has explained the diagnosis of cattle, it can also be used for the diagnosis of other livestock such as horses and sheep.
